A client reference identity of ".example.com" matches a server
certificate presented identity that is any sub-domain of "example.com"

only direct child sub-domains (e.g. "www.sub.example.com").

Fix SEH and stack handling in Win64 build.

(cherry picked from commit 5f4c5a902b0508eab235adecb34b236cdc0048a5)

 * Make a clear distinction between DH and ECDH key exchange.
 * Group all key exchange cipher suite identifiers, first DH then ECDH
 * add descriptions for all supported *DH* identifiers
 * add ECDSA authentication descriptions
 * add example showing how to disable all suites that offer no
   authentication or encryption

Defines SETUP_TEST_FIXTURE and EXECUTE_TEST, and updates ssl/heartbeat_test.c
using these macros. SETUP_TEST_FIXTURE makes use of the new TEST_CASE_NAME
macro, defined to use __func__ or __FUNCTION__ on platforms that support those
symbols, or to use the file name and line number otherwise. This should fix
several reported build problems related to lack of C99 support.

PR#3394

SRP ciphersuites do not have no authentication. They have authentication

default umask followed by a chmod().
